PICO is  a tool you can use to help you create an answerable clinical question. 

It helps create a question that uses evidence-based research to answer.  Not all clinical questions can be answered with research.

Creating a well-built question can be difficult. PICO is a formula that can turn your clinical case into a research question. 

PICO is a mnemonic device which stands for:

• P- Patient or Population or Problem
• I- Intervention
• C- Control
• O- Outcome

• T- Time (sometimes this is added to the end of PICO to represent how long it takes to demonstrate an outcome)
